SUPPORT FOR TROLLEY-WIRES.

SPECIFICATION forming part of Letters Patent No. 582,344, dated May 11, 1897. Application filed March 6, 1897. ia1N 626,338. (No model.)

T0 .60 whom it may concer Be it known that I, EDWARD J. 000K, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of- Ohio, have invented certain new and useful Improvements in Supports for TrolleyJVires, of which the following is a specification.

My invention relates to improvements in the means for supporting trolley-wires, and it especially relates to improvements in the construction of trolley-ears and the means for attaching the same to the trolley-wire.

In the accompanying drawings, Figure 1 is a side elevation, partly broken away, of a trolley ear or support embodying my invention. Fig. 2 is an end view of the same with the Wire in section. Fig. 3 is a similar view showing the position of the parts in attaching the trolley-ear. Figs. at to 8, inclusive, are detail views of some of the various parts, show ing modifications which will be referred to hereinafter.

Like parts are represented by similar letters a of reference in the several views.

ley-wire a and are made sufficiently long to pass below the center of said wire, and thus hold the same in the groove, said groove being chambered out to a larger diameter than the opening through which the wire is inserted.

In order to insert the wire to position, I

form it with a flat side or sides a, which when turned to an unusual position may be inserted through the opening into the groove b after which, by turning the support or wire so as to bring the full diameter of the wire at right angles to the plane of the opening, the wire will be heldin position by the projecting sides 19 and b of the said groove.

To provide for holding the wire in this position and prevent its turning, any suitable means may be employed. In Figs. 1, 2, and 3 I have shown the trolley-ear provided With projections 11 which project from the ends of the trolley-ear in line with the bottom of the groove 12 but which are adapted to be bent down and contact with the flat surface of the wire, as shown in Fig. 2 and at the right of Fig. 1, so as to hold the wire and ear in the proper relative positions to prevent separation of the parts. In Figs. 4 and 5 I have shown the same result accomplished by a wedge or keyb", inserted in the groove above the wire and resting in contact with the fiat side thereof, the bottom of the groove in this case being preferably formed flat instead of round to accommodate the key or wedge.

In Figs. 7 and 8 I have shown the invention adapted for trolley-Wires of different sections, such as are known as the clover-leaf and figure 8 sections. In each of these devices the upper portion (6 is provided with two flattened surfaces d, which join each other at an angle and which will form a cross-section of the supporting portion 0/, of a smaller diameter when the ear is turned to an unusual position than when it is turned to the usual position for use, so as to permit the trolley-ear to be slipped onto the wire in an unusual position and be held firmly thereon when turned to the proper supporting posit-ion.

In practice when the ordinary round section of wire is employed it may be flattened on top at the points at which the trolley-ears are to be attached, as shown in Fig. 6, or a special wire may be drawn having the top flattened throughout its entire length, so that the vertical diameter of the wire will be less than the horizontal diameter, while the distance between the lips b b which form the opening into the groove, will remain fixed and unchangeable.

It will be seen that a trolley-support as thus constructed will be such that the ears may be readily attached or removed, as desired. ordinary practice where the feed-in ears are soldered to the trolley-wire at frequent intervals with the usual strain ears or anchors the devices for holding the wire from turning in the trolley-ear may be dispensed with; but in any event they are easily applied when the parts are joined or removed when the parts are to be separated.

Having thus described my invention, I claim?- l. The combination with a trolley-wire of greater diameter in one direction than in the other direction, a trolley-ear having a chambered groove with an opening less than the diameter of said chamber, said wire being adapted to be inserted into said groove when turned to an unusual position and be held in said groove by the sides thereof when turned to the normal or supporting position, substantially as specified.

2. In combination with a trolley-wire fiattened as described, a trolley-ear having a chambered groove with projecting lips adapted to be inserted over said flattened surface when turned to an unusual position and to engage and hold the sides of said wire when turned to the usual or supporting position, substantially as specified.

3. The combination with a trolley Wire diameter less than the diameter of the main body of said wire, and a trolley-ear having a chambered groove with fixed sides or lips, the opening between which is smaller than the diameter of said wire whereby said trolleyear is adapted to be inserted onto said wire when turned to an unusual position, and means for holding said wire from turning in said trolley-ear in the usual or supporting position, substantially as specified.

4. The combination with the trolley-wire flattened as described, of a trolley-ear having 7 a chambered groove with an opening of less diameter than the main body of said wire,

a said ear being formed with malleable projections adapted to be forced into contact with said wire to prevent the same from turning EDWARD J. COOK.
